List Pages under a Fixed Node

Questions
1

Hi Guys,

I was wonder how do I go about listing pages under a fixed Node. So if I had a node that looks something like this:

Rooms
- Room 1
- Room 2
- Room 3
- Room 4

Using XSLT how would I go about just listing the ROOM 1, ROOM 2... with the XSLT being in the Room Master Page. 

I have been looking at the Code provided by Umbraco to list page under a changeable source but I havent figured out yet how to fix the source to a single node. 

Also is this the best way to go about doing this or is there a better way to achive what im trying to do?

Kind Regards
